Definitions

  • the invention relates to an anti-skidding device for tired, particularly pneumatic-tired vehicle wheels when used on ice and snow.
  • Snow chains are not very popular because it is often difficult to apply them to the vehicle tires and because they must be driven in such a way that the road surface is not damaged, i.e. the snow chains have to be removed on the dry road surface portions following the snow or ice-covered portions.
  • Snow chains are subject to considerable wear and do not permit travelling at high speeds.
  • Snow chains and adhesive tires are often not available, particularly when roads are covered with ice and at short notice, e.g. when the icy surfaces are produced by drizzle or spray falling onto the frozen road surfaces.
  • spiked tires it is not always possible to use spiked tires.
  • starting aids are known, but they are no substitute for snow chains and adhesive tires. These starting aids, which are constituted by clamp straps mounted on the tires, merely assist in moving the vehicle a short distance out of snow or slush.
  • U.S. Pat. No. 2,443,261 discloses an anti-skidding device, which can be fitted to the wheel rims of motor vehicles and which comprises a basic disk and an annular disk rotatable about the centre thereof and on which are articulated pivoted levers for pivoting in and out triangular anti-skidding arms fixed in rotary manner to the basic disk.
  • the anti-skidding arms are pivoted out from a position retracted relative to the tire circumference into a radial operating position, so that the pointed end portions project out of the plane formed by the tire tread and can engaged in the substrate.
  • the anti-skidding arms are also located alongside the tire sidewall in the pivoted out position and in no way engage over the tire thread, so that the increase in the grip of the vehicle wheels does not take place through the direct action of the tire or its tread on the anti-skidding arms or of the anti-skidding arms on the ground surface.
  • the anti-skidding arms do not form an integrated part of the tire in order to achieve an action corresponding to that of spikes embedded in the tread profile of a tire.
  • this known anti-skidding device requires a large amount of space.
  • a further anti-skidding device for vehicle tires known from French Pat. No. 1,368,348 comprises a plurality of arm-like fastenings, which can be attached by means of a basic disk to the rim of a random vehicle wheel.
  • the arm-like fastenings constantly engage over the tread surface in the operating position and when not in use cannot be pivoted out of the tread surface area. When not in use, the complete anti-skidding device must be removed from the rim.
  • a further anti-skidding device described in U.S. Pat. No. 2,610,898 comprises a plurality of spike-like ribs or teeth which, in the operating position, can be laterally extended alongside the tire, but do not engage over the tire tread.
  • the radially arranged anti-skidding arms are pivoted in and out by using a rotatable disk, which can be fitted to a vehicle wheel rim.
  • the anti-skidding arms used in this device are rigid and not resilient-elastic, because they must engage in the ice or snow-covered road surface during the rotation of the wheel.
  • DAS No. 2,750,111 discloses an anti-skidding device for tired, particularly pneumatic tired vehicle wheels, which comprises a supporting casing formed by a basic disk which can be fixed to the wheel disk and an annular disk rotatable with respect to the latter about the disk centre, and at least two equidistant anti-skidding arms, each of which being rotatably mounted on the basic disk and articulated in crank gear-like manner on one end of a pivoted lever, whose other end is rotatably connected with the outer periphery of the annular disk.
  • the anti-skidding arms On rotating the annular disk relative to the basic disk, the anti-skidding arms are pivoted out into a radial operating position from a position retracted with respect to the tire circumference.
  • the pivoted levers and anti-skidding arms are made from spring steel and dimensioned in such a way that the levers transfer the arms from their virtually flat or elongated shape in the starting position into a bent shape projecting into the tire tread in the operating positon.
  • the problem of the present invention is to obviate this problem.
  • the invention solves the problem by providing an anti-skidding device for tired, particularly pneumatic tired vehicle wheels when travelling on snow and ice, which is used for anti-skidding purposes and for increasing the grip of vehicle wheels on snow and ice.
  • an anti-skidding device for tired, particularly pneumatic tired vehicle wheels when travelling on snow and ice which is used for anti-skidding purposes and for increasing the grip of vehicle wheels on snow and ice.
  • the anti-skidding action is obtained by means of spikes, which are held on the tire tread and which, compared with snow chains, can be easily fitted and removed again at any time, whilst having a simple technical construction.
  • an anti-skidding device for tired, particularly pneumatic tired vehicle wheels when used on ice and snow, characterized in that the device comprises an annular cover disk located in the outer surface area of the tire and having a plurality of equidistantly radially fixed anti-skidding arms made from spring steel or resilient-elastic plastic materials, whose free ends are slightly rough bent and wholly or zonally engage over the tire tread and carry on the outside a gripping profile or spikes, as well as a bracing disk for the cover disk mounted on the rim, whereby the anti-skidding arms are pretensioned in such a way that they engage on the tire tread in the operating position.
  • the essential advantages provided by the invention are that only a device constructed in this way provides an effective anti-skidding means for vehicle tires and ensures improved grip of the wheels on ice and snow. Due to the fact that the radially directed anti-skidding arms are made from spring strip steel or resilient-elastic plastic materials and project from the outside of the tire into its tread area, when the tire revolves the ends of the arms pass between the tread profile and the substrate, such as the road.
  • the anti-skidding device has a relatively small number of components and therefore has a simple construction. Thus, its fitting and removal can be effortlessly carried out. In addition, the construction is completely maintenance-free.
  • the requisite tire engagement of the anti-skidding arms is brought about by pretensioning the cover disk and the arms.
  • the mounting of the anti-skidding device on the rim is preferably in the form of a quick-action clamping means, so that the bracing disk is able to brace the cover disk and the anti-skidding arms. By rotating the bracing disk, the bracing action can be removed and consequently the anti-skidding device can be easily detached.
  • the anti-skidding device can be fixed to the rim, e.g. on the flange or in the ventilation openings. Fitting and removal of the anti-skidding device can take place in a very short time and there is no risk of dirtying.
  • each anti-skidding arm comes to rest in the vicinity of the tire tread and as a result of the pretension is pressed against the tread, whilst maintaining the approximately circular arc shape.
  • the anti-skidding device can be manufacture inexpensively because it only consists of a small number of parts. When not in use, the anti-skidding device can be housed in a minimum area so that the possibility exists of mounting this device on a spare tire carried in a vehicle boot or trunk in such a way that the anti-skidding arms engage over the spare tire.
  • the anti-skidding device Since, in addition, the anti-skidding device has a relatively flat construction, several such devices can be effortlessly held in superimposed manner on the spare tire. Due to their arrangement and construction, as well as the pretensioning action, in the operating state the anti-skidding arms automatically adapt to the tire movements.
  • the anti-skidding device simultaneously protects both the vehicle and road due to quiet running. It can be constructed for most standard rims, without any modification to the rim being necessary.
  • the invention also provides a solution according to which an anti-skidding device for tired, particularly pneumatic tired vehicle wheels for use on ice and snow is proposed, which is constructed in such a way that the device comprises a support disk which can be fixed to the wheel disk or rim having a plurality of equidistant, radial anti-skidding arms pivotal about axes running parallel to the wheel disk bearing axis and which are made from a rough-bent profile of plastic or some other suitable material engaging over the tire tread and being provided externally on their free ends with a gripping profile or spikes.
  • the invention also provides a device for fixing the anti-skidding devices to a rim, characterized in that the support disk is fixed to the wheel disk or rim by means of rim screws, wheel studs or screw or bolt fastenings provided on the rim and has openings for the rim screws, and that a locking disk is held on the support disk and is provided with devices locking the rim screw to the support disk.
  • a device constructed in this way prevents vehicle tires from skidding and increases the grip of the wheels on ice and snow. Due to the fact that the anti-skidding arms are pivotally held on the support disk fixed to the rim, the fitting of the device is effortless in that in the contact area between tire and substrate, such as a road or the like, the anti-skidding arms can be swung out sideways and then on starting so engage with the tire tread that they assume a radial position relative to the other arms. The radial forces occurring when travelling are no longer transferred to the basic disk in the case of the present anti-skidding device and are instead absorbed by the pivotable anti-skidding arms. On braking, the anti-skidding arms are placed in front of the tire due to the mass moment of inertia which occurs and consequently increase the braking action. The anti-skidding arms thereby serve as friction-increasing members.
  • the anti-skidding arms are made from plastic materials, have a certain resilient-elastic behaviour and are provided with a material reinforcement in the bent end area, when travelling the free ends of the anti-skidding arms only lift to a very limited extent from the tire tread.
  • the anti-skidding arms are pressed onto the tire tread, snow and ice which has been collected between the anti-skidding arms and the tread is forced out due to the interaction between the pressing and lifting effect.
  • this lifting effect only occurs in the vicinity of the bent free ends of the arms and is extremely small.
  • the anti-skidding arms assume a radial and equidistant position. The pivotability of the arms is a valuable aid in fitting the anti-skidding device and also assists the braking action.
  • the arms When travelling, the arms always assume a vertical position and have a long life, due to the fact that they are made from plastic.
  • Fitting the anti-skidding device is effortless and merely involves placing on the rim screws fixed to the rim.
  • the support disk carrying the anti-skidding arms is placed on the rim screws in such a way that their head-like ends project through the openings provided in the support disk.
  • the locking disk rotatably arranged on the support disk is provided with gripping devices in such a way that on rotating the rotary disk, the support disk is locked with the rim screws.
  • the locking to the rim screws is detachable, so that the anti-skidding device can be easily removed.
  • the anti-skidding arms engage over the vehicle tire on the tread side.
  • the free end of each arm comes to rest in the vicinity of the tire tread.
  • the anti-skidding arms are preferably made from resilient-elastic plastics and have a rough-bent profile, the possibility exists of adapting the arms to the tire cross-sectional profile in such a way that the free end of each arm comes to rest between the tread and the substrate when the vehicle is travelling and when the wheel is revolving. Due to the fact that the arms come to rest between the tread and the substrate, very good adhesion of the tire to the substrate is achieved. In this way, it is possible for this anti-skidding device to achieve the same effect as that obtained with spiked tires.
  • the anti-skidding device can be manufactured in an inexpensive manner, because it only comprises a few parts. When not in use, the anti-skidding device can be housed in a very small area, which makes it possible for the anti-skidding device to be fitted on the spare tire carried in the vehicle trunk or boot in such a way that the anti-skidding arms engage over the spare wheel tire. Since, in addition, the anti-skidding device has a relatively flat construction, a plurality of anti-skidding devices can be held without difficulty in superimposed manner on the spare tire. Due to their arrangement and construction in the operating state the anti-skidding arms automatically adapt to the tire movements.
  • the anti-skidding device simultaneously protects the vehicle and road through quiet running. It can be constructed for most standard rims, without any modification to the latter being necessary, because the anti-skidding device is fixed by means of rim screws, which have a special construction for this purpose. In those cases when the rims are held by nuts on the wheel bolts, the construction of the nuts is adapted to the rim screws, so that here again effortless fixing of the anti-skidding device is possible.

  • openings 136 are constructed as elongated holes and are arranged in basic disk 130 in such a way that the openings 136 with their longitudinal axis come to rest in a radial manner.
  • each opening 136 can have a circular portion 136a, whose diameter is larger than that of rim screw 116, note FIG. 8. This circular portion 136a is followed by an elongated hole-like portion 136b, whose diameter corresponds to that of the annular slot 262 of rim screw 116.
  • Openings 136 are arranged in basic disk 130 in such a way that portions 136b are located on a circular arc-like line.
  • the anti-skidding device 100 is locked to the rim screws 116 solely through the rotation of basic disk 130, so that portions 136b come to rest in the vicinity of annular slots 262 of the rim screws 116, so that the locking action is obtained.
  • basic disk 130 is rotatably mounted in support disk 20.
  • basic disk 130 is provided with a handle, not shown in the drawing, in order to be able to rotate disk 130 for locking purposes.
  • Locking disk 150 is provided with a handle not shown in the drawing, so that said disk can be rotated about its rotation axis 151 for locking purposes.
  • the number of arms 152 carrying the semicircular engagement recesses 153 and provided on locking disk 150 corresponds to the number of rim screws 116 used.
  • the engagement recesses 153 are arranged on arms 152 of locking disk 150 in such a way that on rotating disk 150 in the direction of arrow X, recesses 153 are at the front and consequently engage with the annular slots 262 of rim screws 116.
  • Support disk 120 or basic disk 130 is so arranged relative to rim screws 116 when the anti-skidding device 100 is fitted, that it comes to rest roughly in the plane formed by the shoulder-like portions 263 of rim screws 116, so that the arms 152 of the plate-like locking disk 150 arranged on support disk 120 or basic disk 130 comes to rest in the plane formed by the annular slots 262 of screws 116.
  • its engagement recesses 153 engage in the annular slots 262 of rim screws 116.
  • the radial arrangement of openings 136 in basic disk 130 also provides the advantage that it is possible to align the anti-skidding device 100 with the rim screws 116 during the fixing process.
  • the areas of arms 152 adjacent to engagement recesses 153 overlap the areas of openings 136 remaining around the rim screws 116 placed through the openings, so that a firm seat of anti-skidding device 100 on wheel 11 is achieved.
  • the previously described locking device shown in the drawing can also be replaced by differently constructed locking devices. It is essential to bring about locking with the aid of rim screws 116 as a result of the construction thereof.
  • the locking disk 150 arranged on support disk 120 or basic disk 130 is covered by a cover disk 160 held either on disk 120 or disk 130 in such a way that the rotation of disk 150 is in no way impaired (FIG. 7).
  • Cover disk 160 is provided with an opening 161 through which can pass a handle, not shown in the drawing and fixed to rotary disk 150.
  • cover disk 160 has a number of inspection window-like openings corresponding to the number of rim fixing screws. Cover disk 160 can be held in rotary manner on disk 120 or disk 130 with gripping profiles for manual actuation and can be connected to locking disk 150.
  • support disk 120 is fixed to basic disk 130 or if support disk 120 simultaneously constitutes basic disk 130, then the anti-skidding arms 140 are pivotably mounted on the circumference of support disk 120 by means of pivot means. This pivotability of the anti-skidding arms is achieved by riveted or screwed connections 170, which are such that the pivotability of arms 140 in the direction of arrow X1 is not impaired (FIGS. 7 and 14). Support disk 120 is then provided with an all-round extended portion 120a engaging over the articulation area for anti-skidding arms 140.
  • support disk 120 it is also possible to hold support disk 120 on basic disk 130 in rotary manner.
  • basic disk 130 is locked with rim screws 116 by means of locking disk 150.
  • disk 120 can be rotated about disk 130.
  • anti-skidding arms 140 are fixed on support disk 120, so that through the possibility of rotating support disk 120 a small position change of arms 140 engaged on tire 113 is possible.
  • the number of anti-skidding arms 140 fixed to support disk 120 is a function of the size of the tire 13 to be provided with the anti-skidding device.
  • support disk 120 can have arm-like extensions 121, which can be pivotally held on arms 140 and which externally engage over the latter (FIG. 6).
  • Locking disk 150 is connected to an arresting device 255 in such a way that when locking to the rim screws has taken place, locking disk 150 cannot become automatically detached from its locking position, this only being possible after releasing the arresting device, which can be constructed as a push-button catch (FIG. 12).
  • locking disk 150 is then constructed as a circular device 250a, in whose circumferential area is arranged the arresting device 255, locking disk 250a being provided with a stop 255a which cooperates with the arresting device.
